In the next weeks, I will show you some games that can be installed and played on your Raspberry Pi without an emulator. This games are often available from your packet manager, so it is very easy to install them. Many games are Open Source versions of classic games which are now playable on ARM processors too.
Raspberry Pi games
A really good site that I found is here. Someone did the job to evaluate games that are available from the packet manager and started to check if they are playable on Raspberry Pi. Some of them are yet tested and work without problems, others are too heavy for the Pi. I will get you some highlights of this list and I will show you the best playable games for your Raspberry Pi. Stay tuned!
